A JETSTREAM LANDED AT A CTLED ARPT WITHOUT LNDG CLRNC.

Narrative

VECTORING US TO THE FINAL APCH COURSE; APCH CTL CLRED US FOR THE VISUAL APCH ABOUT 8 MI FROM THE RWY. HOWEVER; THEY DID NOT HAND US OFF TO TWR AT THAT TIME. MY CAPT AND I WERE BUSY COMPLETING THE APCH CHKLIST FOR WHAT WAS THE LAST FLT OF A LONG; LONG 3 DAY SEQUENCE. WE HAD FLOWN 5 LEGS THE FIRST DAY; 8 LEGS THE SECOND DAY; AND 5 LEGS THIS DAY BEFORE XA30. WE WERE BOTH SO FOCUSED ON MAKING A GOOD APCH AND LNDG THAT NEITHER ONE OF US NOTICED WE HAD STILL NOT RECEIVED A HDOF FROM APCH CTL UNTIL WE HAD LANDED AND WERE TURNING OFF THE RWY. I IMMEDIATELY CONTACTED THE TWR; APOLOGIZED AND EXPLAINED WHAT HAD HAPPENED. TWR INSTRUCTED US TO HOLD SHORT OF THE PARALLEL RWY AND SAID NOTHING ELSE. IN HINDSIGHT; I THINK 2 CONTRIBUTING FACTORS WERE LARGELY TO BLAME. FIRST AND FOREMOST WAS SIMPLY PLT FATIGUE. ALTHOUGH IT IS WITHIN REGS; 14 HR DAYS CONSISTING OF 8 AND 9 LEGS SIMPLY TRANSLATES TO FATIGUE; AND THE ACTUAL AMOUNT OF REST AND SLEEP WE RECEIVE IS TOO LITTLE TO COMPENSATE. PERHAPS THE BIGGEST PROB IS RECOGNIZING THE FATIGUE. AT MY REGIONAL AIRLINE WE FLY THIS WAY ALL OF THE TIME. OUR PLTS LIVE THEIR ENTIRE WORK LIVES IN A PERPETUAL STATE OF FATIGUE. ALSO; THE APCH CTLRS AT THE ARPT WHETHER SEEMINGLY BUSY OR SLOW; FREQUENTLY FORGOT TO HAND US OFF TO THE TWR. UNFORTUNATELY; THIS IS OFTEN THE BUSIEST TIME ON THE FLT DECK; AND THEREFORE; IT IS EASY TO LOSE TRACK OF WHETHER ONE HAS RECEIVED THE HDOF.
